Even fountain pens of the same brand can have vastly different lifespans depending on how they are used and maintained. Although there are many types of fountain pens, the basic rules of use and care are similar.
1. Correct Writing Posture
Some writers, wanting finer lines, tend to write with the side or back of the nib. In fact, the reverse side of the nib is less finely finished than the front; writing with the reverse side produces rough strokes with little spring. Over time, this also affects the normal flexibility of the front side, causing uneven ink flow and inconsistent line width. Writing with the side of the nib is equally problematic, as the slit does not directly contact the paper and ink flow becomes rough. Moreover, using only one tine of the iridium tip wears it down unevenly — one side wears away while the other remains intact, destroying coordination and eventually making the pen unusable.
The correct writing posture is to place the front of the nib squarely on the paper, keeping the pen at an angle of 45 to 75 degrees to the paper surface.
2. Moderate Pressure
Too much pressure spreads the iridium tip apart, causing the nib to catch on paper or even break the tip. Too little pressure affects ink flow.
3. Do Not Mix Inks
Different brands of ink have different compositions and formulas. Mixing them can cause chemical reactions, produce sediment, and damage the ink sac, obstructing smooth flow. It is best to consistently use one brand of ink. If you must switch to another ink, thoroughly clean the ink sac with clean water first. Keep the ink sac adequately filled — do not wait until it is completely empty before refilling. When the sac has little ink and more air, writing may cause ink to flow too fast or leak. When drawing ink, do not let the nib touch the bottom of the bottle, to avoid damaging it.
4. Keep Nib and Section Clean and Dry
Wipe clean after filling with ink. Regularly rinse the ink sac and the feed channel with water.
5. Do Not Fidget with the Clip
A pen clip is typically rated for about 10,000 uses (one use = clipping on and off a pocket). Idly playing with the clip will inevitably shorten its lifespan.
6. Cap Immediately After Use
Always put the cap back on after using the pen.
7. Clean Before Long-Term Storage
If the pen will not be used for an extended period, clean it thoroughly before storing; otherwise, residue build-up can affect future writing.
